Abstract
Description
Technical Field
[0001] This utility model relates to the field of lamination equipment technology, and in particular to a circuit board lamination equipment. Background Technology
[0002] The existing multilayer circuit board production process achieves layer addition through lamination, with each circuit board bonded together by resin. Currently, for large circuit boards, the resin cannot be evenly applied between the circuit boards. This results in the resin not being able to fully fill the tanks during the lamination process. After the resin solidifies, the unfilled tanks are exposed to the air, increasing the corrosion rate of the circuit boards.
[0003] In addition, the circuit board does not have the function of scraping off the extruded resin during the lamination process. After lamination, the extruded and solidified resin edges need to be cut off, which increases the processing steps. Therefore, a circuit board lamination equipment is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the prior art by proposing a circuit board laminating device.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A circuit board laminating device includes a base, a mounting bracket fixedly connected to the top of the base, a hydraulic cylinder mounted on the top of the mounting bracket, a laminating plate fixedly connected to the output end of the hydraulic cylinder, a square opening at the top of the base, a laminating table slidably connected to the inner side of the square opening, a guide seat slidably disposed at the bottom inner side of the base, sliding openings on the four side walls of the base, a U-shaped movable support plate fixedly connected to the guide seat slidably disposed inside the sliding opening, and a glue scraping assembly disposed at one end of the U-shaped movable support plate.
[0007] Preferably, the top of the base is provided with a recycling box for recycling resin, the top of the base is provided with an insertion hole, and the bottom of the recycling box is fixedly connected with an insertion shaft that is inserted into the insertion hole.
[0008] Preferably, the bottom end of the pressing table is provided with a turning groove, and a roller is rotatably arranged on the inner side of the turning groove.
[0009] Preferably, the inclined surface of the guide seat is provided with multiple rubber protrusions, and a return spring is fixedly connected to one end of the guide seat, with one end of the return spring fixedly connected to the inner wall of the base.
[0010] Preferably, the adhesive scraping assembly includes a fixed frame plate fixedly connected to one end of the U-shaped movable support plate, a drive screw is rotatably disposed inside the fixed frame plate, a nut block is threadedly connected to the surface of the drive screw, and an adhesive scraping block is fixedly connected to one end of the nut block.
[0011] Preferably, a forward and reverse motor is installed at one end of the fixed frame plate, and the output end of the forward and reverse motor is fixedly connected to the drive screw.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This solution is equipped with a scraper assembly and guide seats. When the circuit board is placed on the pressing table, the circuit board moves downward under its own weight, causing the pressing table to move. This causes the rollers to press the inclined surface of the guide table downward, causing the guide tables to gather towards the center of the pressing table. Then, the scraper assembly moves through the U-shaped moving support plate, so that the scraper blocks contact and push the circuit board, positioning the circuit board at the center of the pressing table, thus realizing the automatic positioning and clamping function of the circuit board.
[0014] 2. This solution is equipped with a guide seat, and the inclined surface of the guide seat is provided with rubber protrusions. When the roller rolls on the inclined surface of the guide seat, the roller will drive the pressing table to vibrate, which in turn drives the circuit board to vibrate. This allows the resin on the surface of the circuit board to be evenly dispersed, improving the uniformity of resin coating and ensuring that all grooves on the circuit board can be filled with resin.
[0015] 3. This solution incorporates a scraper assembly that uses a reciprocating motor to drive the scraper block to move back and forth, thereby scraping off the extruded resin and preventing it from solidifying at the edges of the circuit board. It also allows for the recycling of excess resin. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Reference Figure 1-4 A circuit board pressing device includes a base 1, a mounting frame 3 fixedly connected to the top of the base 1, a hydraulic cylinder 4 mounted on the top of the mounting frame 3, a pressing plate 5 fixedly connected to the output end of the hydraulic cylinder 4, a square opening at the top of the base 1, a pressing table 2 slidably connected to the inner side of the square opening, the pressing table 2 having the same specifications as the circuit board, and a guide seat 12 slidably provided at the bottom inner side of the base 1, the guide seat 12 being distributed according to the specifications of the circuit board to ensure that when the roller 14 rolls to the bottom of the inclined surface of the guide seat 12, the scraping blocks 9 at each point just contact the edge of the circuit board;
[0023] Furthermore, a turning groove is provided at the bottom of the pressing table 2, and a roller 14 is rotatably arranged on the inner side of the turning groove. Furthermore, multiple rubber protrusions 11 are provided on the inclined surface of the guide seat 12, and a return spring 13 is fixedly connected to one end of the guide seat 12. One end of the return spring 13 is fixedly connected to the inner wall of the base 1.
[0024] It should be noted that when the pressing table 2 moves downward, the roller 14 will press down on the inclined surface of the guide seat 12, thereby generating a horizontal component force towards the center of the pressing table 2, which in turn pushes the guide seats 12 in various places to move towards the center of the pressing table 2, providing driving force for the automatic positioning and clamping of the circuit board by the scraping assembly.
[0025] It should be noted that the rubber protrusion 11 is designed so that when the roller 14 rolls on the inclined surface of the guide seat 12, the roller 14 will vibrate, which in turn drives the pressing table 2 to vibrate. The pressing table 2 drives the circuit board to vibrate, so that the resin on the surface of the circuit board can be evenly distributed on the surface of the circuit board under the action of vibration, ensuring that all the grooves on the circuit board can be filled with resin.
[0026] It is worth noting that when the pressing table 2 is initially in its position, its top end is higher than the bottom end of the scraper block 9. When the scraper block 9 contacts the edge of the circuit board, the bottom end of the scraper block 9 is flush with the top end of the pressing table 2.
[0027] It is worth noting that when the scraper block 9 contacts the edge of the circuit board, the roller 14 rolls to the bottom of the inclined surface of the guide seat 12. When the pressing plate 5 presses down on the circuit board, the pressing table 2 will not continue to move down, that is, the scraper block 9 will not move.
[0028] The base 1 has sliding openings on its four sides. A U-shaped movable support plate 7, which is fixedly connected to the guide seat 12, is slidably arranged inside the sliding openings. A scraping component is provided at one end of the U-shaped movable support plate 7. Further, the scraping component includes a fixed frame plate 8 fixedly connected to one end of the U-shaped movable support plate 7. A drive screw 6 is rotatably arranged inside the fixed frame plate 8. A nut block is threadedly connected to the surface of the drive screw 6. A scraping block 9 is fixedly connected to one end of the nut block. Further, a forward and reverse motor 15 is installed at one end of the fixed frame plate 8. The output end of the forward and reverse motor 15 is fixedly connected to the drive screw 6.
[0029] It should be noted that: when the forward and reverse motor 15 is turned on, the forward and reverse motor 15 drives the drive screw 6 to rotate intermittently in the forward and reverse directions, so that the nut block drives the scraper block 9 to move back and forth along the drive screw 6. This can scrape off the excess resin squeezed out during the pressing process. The scraped resin drips into the recycling box 10 for recycling, which avoids the excess resin from solidifying at the edge of the circuit board. This eliminates the need for subsequent resin cutting operations at the edge of the circuit board, reducing processing steps.
[0030] Furthermore, a recycling box 10 for recycling resin is provided at the top of the base 1, and an insertion hole is provided at the top of the base 1. An insertion shaft that is inserted into the insertion hole is fixedly connected to the bottom of the recycling box 10.
[0031] It should be noted that the insertion shaft and insertion hole make it easy to remove the recycling box 10 from the base 1, which facilitates the cleaning of the recycled resin inside.
[0032] When this utility model is used, the circuit board to be pressed is placed on the pressing table 2. Under the action of the circuit board's own weight, the pressing table 2 moves downward, causing the roller 14 to press down on the inclined surface of the guide table, causing the guide tables to gather towards the center of the pressing table 2. Then, the U-shaped moving support plate 7 drives the scraper assembly to move, so that the scraper blocks 9 contact and push the circuit board, positioning the circuit board at the center of the pressing table 2 (at this time, since the pressing table 2 and the circuit board have the same specifications, the edge of the circuit board is flush with the edge of the pressing table 2), realizing the automatic positioning and clamping function of the circuit board.
[0033] When the roller 14 rolls on the inclined surface of the guide seat 12, the roller 14 will vibrate, which in turn drives the pressing table 2 to vibrate. The pressing table 2 drives the circuit board to vibrate, so that the resin on the surface of the circuit board can be evenly distributed on the surface of the circuit board under the action of vibration, ensuring that all the grooves on the circuit board can be filled with resin.
[0034] Then, the hydraulic cylinder 4 is activated. The output end of the hydraulic cylinder 4 drives the pressing plate 5 to move downward. The pressing plate 5 will press the circuit board downward to achieve the pressing function of the circuit board. During the pressing process, excess resin on the surface of the circuit board will be squeezed out. At this time, the forward and reverse motor 15 is activated. The forward and reverse motor 15 drives the drive screw 6 to rotate forward and reverse intermittently, so that the nut block drives the scraper block 9 to move back and forth along the drive screw 6. The excess resin squeezed out during the pressing process can be scraped off. The scraped resin drips into the recycling box 10 for recycling, avoiding the excess resin from solidifying at the edge of the circuit board. There is no need to cut off the resin at the edge of the circuit board afterward, reducing the processing steps.
[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
